at least a portion of mounting flanges of the insulation on the face oithe studs, each studface having the edges of opposed flanges spacedapart. Ordinarily, these portions of the anges are secured to the facedirectly, or. indirectly by mounting wall board or a plaster base overthe fianges. Because spaced points of attachment along the fiange havebeen used, there have been left open spaces or vents through which airmoves. warm side to the cold side of the insulation by way of thesecracks, openings or vents, may be serious where conditions createcondensation of moisture. In warm air, the moisture content is high, andthis is particularly so in air-conditioned rooms in winter. This moistwarm air moving to the cold side becomes chilled and moisture is,deposited as free water. This water may run elsewhere, soak thestructure or even the insulation, and continue to collect and do damagebefore it may dry out. And it may never dry out of certain constructionsproducing rot or other damage. Furthermore, this free water may freezeand gradually accumulate ice. This may also create trouble in numerousWays. Particularly it may collect and fall, perhaps breaking insulationby sheer weight.

Itis therefore of great value to provide a wall,

forms of the invention shown in the accompanying drawing in which:

Fig. 1 represents one insulating structure wherein the invention may beused.

Fig. 2 is l,another type of insulating structure wherein the inventionmay be used.

Movement of air, particularly from the opposite faces.

Figs. 3,4, 5, 6, a and 9 are detailed structures illustrating theinvention as applied to a structure according to Fig. 1.

' Fig. 7 is a detailed view of one sealing means' for use in a structurelike that of Fig. 6.

Fig. 10 is another detailed view of a structure according to theinvention, additionally representing an application over the studs onthe warm side of a wall.

- Fig. 1 represents a wall having the preferred type of insulation I 0whether rigid or flexible, mounted on studs by angular anges I2 whichhave a portion I3 on the side of the stud and a portion I4 on the faceof the stud. Thus the insulation has its face inwardly from the face ofthe studs. 'I'he dotted circles I5 are diagrammatic to represent thedetailed structures later described. It is of course to be understoodthat the insulation itself may be or have a seal against passage of airdirectly through the insulation between studs. of the insulation I0 havewater-proof or moisture-vaporproof and air-tight liners, as of paper |6and which in the preferred form is an asphalted creped paper, so as toyield without rupture, in handling, mounting, and in settling of thestructure.

Fig. 2 represents what may be rigid` or exible insulation. For example,rigid mineral-fiber bats are shown, which have a liner 2| of airtightpaper, which is also desirably Water-proof. and moisture-vapor-proof.Liner 2| extends laterally to provide anges on the face of the studs 22.These flanges need not be mounting flanges, for such bats can be placedwithout necessarily'securing the ange to the studs. The dotted circles,23 are diagrammatic to represent the detailed uniting structuresdescribed below The insulation 20 is shown with a space behind it, butit is to be understood that it may be the wall thickv Variety whichcompletely fills the space between the finishing structures on thestuds. This type is extremely subjectto damlating space.l

In Fig. 3, a stud is shown with face 26 I whereon the seal is formed.Two flanges 2l and 28 lie on the face 26.` Each ange is shown as anangular flange, described for Fig. 1, having a reinforcing angular strip29, as of scoredY chipboard, enclosed within liners 30 and 3| on its Theliners may be paper, as for example, extended portions of the liners I6and I1 of the insulation in Fig. 1. Liners 3D and 3| may be onecontinuous piece as shown in Fig. 3.

Preferably, both faces In Fig. 3 these liners terminate in a cooperativemanner to effect the seal, one to the other. The continuous liner Sil-3|on one flange 21 is folded in to provide two lips 32 and 33 defining agroove 34, for receipt of tongue 35, formed by a fiat fold in thecontinuous liner 30-3I of the other fiange 28. In mounting, the tongueand groove union is completed preferably in the presence of a sealingmaterial such as asphalt 36. The groove 34 may contain soft asphalt orplastic adhesive, such as to permit pulling the lips apart for insertionof the tongue 35.

It is noted that the true dimensions of the flange parts, relative tothe stud, are exaggerated merely f'or the purpose of illustration.'I'his holds true forall of the illustrations. The angular flange withreinforcement is more particularly described in the copendingapplication of Edwin W. Davis, Serial No. 221,068, filed July 25, 1938.

In Fig. 4 the respective liners 30 and 3| are separate, and the ends 38of one set merely include the ends 39 of the opposite flange. Sealingmaterial 40 is shown. This may be carried between the liners asdescribed above for groove 34. The dotted line 38' represents one flapfolded out, with adhesive 40' exposed on opening the strip to be foldedin onto liner ends 39 when the two flanges are united.

Fig. represents a modified structure in which a stud 42 has two flanges43 and 44 of the groove" types above described. They present the grooves45 and 46 into which fits a single strip or "double-edged-tongue" 41.Adhesive may be used as shown.

Fig. 6 shows a modified form in which a stud 50 has two flanges 5| and52 each of the tongue type. These have reinforcing members 53 extendingnot quite to the edge of the tongue insideliners 54 and 55,so that theedge is thin. An auxiliary double-edged groove element is provided inthe form of a strip 56 presenting edge grooves 51 and 58 by suitablestructure. Fig. 7 shows such a convenient tongue-strip comprising twostrips of' material 59 and 60, which may be secured together near theircenters. This may be done by staples 6| securing both strips to thestud.

The forms of Figs. 4, 5 and 6 provide two like flanges for a strip ofinsulation, and are preferred to a form like Fig. 3 'wherein two typesof flange are required. Still another type having different flanges isshown in Fig. 8. Stud '65 has flanges 66 and 61 with clinching endfolds.

flange 66 is turned ln and under as shown at 66.

. while the edge of flange 61 is turned out and over as shown at 69, theparts clinching as shown.`

Sealing adhesive is to perfect the seal.

A particular advantage of the flanges comprising the thicker reinforcingstrip covered by one or two liners, the reinforcing stripsterminatpreferably used in the Joint ing short of the edge line of theflange, lies in` the fact that the sealed joint is at least not thicker,and preferably thinner, than the reinforced area of the flange. There isthus no bulging central line along the face of the studs as a result ofthe new construction. It is also to be understood that in the form ofFig. 4, the thinner edges of one flange may be lapped entirely over thethinner edges of the other flange, without the "tongue and groove union,or one liner of each flange may fit between the two liners of the otherflange.

The invention may be employed in other forms The edge of'A such as inFig. 9 and Fig. 10. In Fig. 9 a stud 1U has flanges 1| and 12, each withthin edges 13 and 14, each not over half the greater thickness, whichedges do not reach to each other. A sealing tape 15 is placed to formthe joint or seal over the thin edges but not over the thicker portions.

In Fig. 10, the stud 16 receives flanges 11 and 18 with thin edges 19and 80, each not over half the greater thickness of the flange portionof the stud face. The anges are long enough for only the thinner edgesto overlap, with intervening adhesive 8|.

In Fig. l0 wall board or plaster-base is shown mounted over the flangeslying on the face of stud 16. It is common to make a joint in thesematerials over the center of the stud face. particularly with wallboard. Two sectionsv 83 and 84 of such material are shown so joined, andnailed to the stud by nails 85 and 86. with the joint covered by beading31 or other strip material. Flush joint constructions are alsocontemplated. The nailing is located laterally of the stud-face center,coming of the flange.

as asphalt the flanges and also to the stud. Herethe term strip-likemeans is used to united to in where designate the sealing element, it isto be understood that it may be integral with a flange, attached.initially to a flange, or separate from a flange.

The present invention makes an excellent element for an insulated wallwhen carrying out ythe invention of the Weyerhaeuser-Busch U. S. PatentNo. 2,030,668.

It is readily seen that any of the detailed structures described may beused where the dotted circles 5 and 23 appear respectively in Figs. land 2.

It is noted that in Fig. l the liner |1, as the warm side liner islittle exposed to moisture or water. But liner I6 should protect theinsulation on the cold side from condensation of any moisture which mayhave moved from the room into the cold side of the wall. Therefore, theparticular liner 6 is preferred to be of water-proof material,regardless of what material liner |1 may be. In a structure like Fig. 2,the insulation is open to receive moisture condensing from air leakingin around the stud (in cases needing the present invention). Ice mayreadily accumulate on the cold face of the insulation. As it gets heavyit is free to drop down in the residual space illustrated. Thisgradually destroys the4 insulation. The only remedy is avoidance of theconditions, and the present invention provides a simple and convenientWay to help in the avoidance. The sealing need not be, and

"two portions .body including reinforcing the flange, said reinforcingmaterial being absent 'practically is never perfect with ordinaryexpense and-workmanship. But slight accumulation of moisture ispermissible where the remainder of the construction is such as to permitdrying out. However, closeness to perfection is the goal to be sought,because wet insulation ceases to insulate. Therefore, sealed insulation,as shown in Fig. l is the preferred form.

Various modifications vand applications of the invention will occur tothose skilled in the art without departing from the spirit and scope ofthe invention as expressed lin the appended claims.
